As a user of Jira, we update the Fix Version of Epics. This does not reflect in Aha! in the Release unless we also add some data in another field such as description. This is very frustrating for users of Jira and Aha! as they should be able to update a field that is mapped to Aha! and have that update appear. This is a great deterrent to our users to even trust Aha! or use it.
Thank you for the idea.
Someone from our Customer Success team will reach out to you shortly to learn more about your use case to see if they can help further as I was not able to reproduce your issue.
